Physical concepts in optical communication

Overall Course Objectives

To enable the student to 1) apply his fundamental knowledge in optics and photonics to concrete issues in optical communications. 2) to understand how essential physical mechanisms can be applied to the generation, transmission and detection of optical data in high-speed optical communication systems. 3) to realize that future improvements in state-of-the-art optical transmission technology will rely on a thorough understanding of fundamental physical issues.

relate physical properties of the gain mechanisms to amplifier performance (gain and noise figure) in Raman amplifiers and erbium doped fibre amplifiers
analyse gain and noise performance of erbium doped fibre amplifiers and Raman amplifiers with respect to application in optical communication systems
compare performance of erbium doped fibre amplifiers against Raman amplifiers and parametric amplifiers
Explain the propagation properties of integrated dielectric waveguides and the effects in silicon used to modulate data signals
apply basic knowledge of electromagnetic theory to analyse the propagation of electromagnetic waves in anisotropic media
analyse how the linear electro-optic effect can be exploited to modulate the properties of an electromagnetic field
apply the linear electro-optic effect to the modulation of lightwaves for use in optical communication systems
